They're both quite good but quite honestly I prefer Pandora and it's MUCH better UI in my opinion. I've been using it off and on for the 6month trial Plus one additional month paid. The only thing that will likely hold me back from continuing is the lack of Sonos integration thus far, which they've promised for months still with no real info as to when it'll happen. I'm leaving for the time being due to this but when/if it does happen I'll gladly be back. Spotify is great in many ways but I've never grown comfortable with their UI, mobile or desktop and always find it cludgy , cluttered and unintuitive .
